Would Mahan have ordered dreadnoughts in 1905?

Would Mahan have built a dreadnought in 1905 instead of ordering more pre-dreadnoughts?

Mahan favored the concept once it appeared, but the chronology used here allows an order around 1904 followed by roughly two years of construction.

The chronology used here places the emergence of the all-big-gun concept around 1903 and allows roughly two years for construction after an order. On that basis, an order in 1904 would not produce a completed ship in 1905. Mahan favored the concept once it appeared. American ordering is judged to have followed about as quickly as this development and construction timetable allowed.
